BEIJER E300-02750D｜HMI Automation｜
The E300-02750D belongs to Beijer’s E300 series, designed for small and medium automation projects requiring higher performance.
Its core advantage is “balanced functionality + strong scene adaptability”:
Meets the basic interaction needs of small/medium automation equipment.
Adapts to segmented industrial scenarios through the specific “D” configuration suffix (e.g. Ethernet interface, enhanced communication).
Typical applications:
Local operation/status display of PLC control systems (Siemens S7-200 SMART, Mitsubishi FX3U, Delta DVP).
Centralized monitoring of devices needing stable data exchange and basic network connectivity (frequency converters, servo drives, temperature controllers).
Situations with strict requirements for communication interfaces or protocol compatibility (simultaneous PLC + upper-computer connections, third-party private protocols).
Embedded cabinet-door installation in dusty, humid industrial workshops (food processing, machinery manufacturing, etc.).
Technical Specifications
